The RC1220 high-performance, 12-in.-capacity chipper features VersaFeed infeed control and the X-Charge discharge system to deliver more air velocity to optimize discharge and prevent plugging. The unit is powered by a 67- or 99-hp Kubota diesel engine. The feed wheel measures 20 in. in diameter and is powered by a maintenance-free planetary motor. The 12-in. high by 20-in. wide infeed opening easily feeds stubborn material. The hydraulic feed wheel can be operated from either side of the machine.
